How do I concatenate two strings in C?

Question

How do I add two strings?

I tried name = \"derp\" + \"herp\";, but I got an error:

Expression must have integral or enum type

Answer 1

You cannot add string literals like that in C. You have to create a buffer of size of string literal one + string literal two + a byte for null termination character and copy the corresponding literals to that buffer and also make sure that it is null terminated. Or you can use library functions like strcat.
